'pplica'tion to, the ordinary forms offwheels. [This is so liremoyably in place. It 4willjbe understood thatin .orderto're'- 'ove'thetire casing fromits position on the f r1m,.itn1s necessary to detach lthev locking' ring l8'andthen'manuallyjtofforce'the.cas-75 y ilitlvoiiinthefdirection 'ofthe arrow. Where `t l1`e `ri1n is level or of uniform diameter at either-side, the= frictional engagement liey tween the ianges 1 6 and periphery Aof the 4z va metal``rnn,` rim vc'ontinues with, the same" pressure 80 tire for along -lthroughoutthe entire'in'ovenient` ofthe fin-1 side.;langed bearing `across 'thef'fullf :width 4of the rim. Manifestly, itf-becomes a di'ili-4 en ltftask to drag theunyieldinganges 1,6. i' this distance, and particularly 'so because of4 {8 5' the' disposit1on ofthe corner 20g-of ,the infj side iangexwhich, upon '.meetingwithjrestraint, is caused to move inwardly and thus increase the friction between thefparts.

By beveling or slanting the peripheral surface of the rim', as shown,'the extent of v excessive rictionall engagement is considerably shortened, sothat, after the initial movement of the tire, such as would be necessary to break 'its seal, the parts become freed and the easingA can be bodily with; drawn Without difficulty when the beveled ring 16 'has first been removed. The extent of slanting or beveling of therim need lnot be great as a slight variation is sulicient to relieve friction and overcome the binding action of the corner 20 in removing the tire, Obviously, the same advantages present when removing the tire apply also when putting a tire in place.

l employ thek beveledring 16 which is adapted to it on the outer edge of the slanted rim 12 and be of such thickness as to offset. the slanting, of the rim so that the ordinary 'form .of casing, when applied thereto, will be given a level setting. The

ring 1 6 is preferably split to .facilitate refriction between thebearingportion of the-I ing a tire into' position'thereomcontinues during the 'entire movement of the ,tire-. across the rim; This varies j in` distance from three to four inches in ordinaryinstances. Aside from this,

can be exerted suieient to slide a snugly this rusted expanse loit rim. Manyy attempts have been made toi. overcome this difficulty, but none, so far as: known to me, has been of practical form, or has ever come into use. Imeet the prob lem and effectually solve it by the simple provision of a' Wheel rim which will have a thel outer .side oit', its periphery than at the inner side thereof, by reason of which the bearingvfiangesof the tire casing will not come into frictio'nal engagement with the wheel rim until' they have almost reached'their ultimateposition made use of on the outer rim to provide an even setting for the tire.` i V One form which myA invention may assume is exempliiedin the following description and illustrated. in the accompanying drawings, in which- Figure 1 shows across sectionalview of a portion'of'a wheel and ire embodying my shows a similar view, illustrating a portion of the wheel rim. Fig. 3 shows a side elevation of a portion ofl a wheel', Fig. 4 shows a side view Iof the Wheel, with the tire applied` thereto.

able beveled ringis fer, however, the form shown, on account of.

its simplicity and economy of construction; the rim being of uniform thickness throughout its width can be shaped in ordinary rollers. y,

I provide animproved and simplified fastening for the slanted rim, comprising a ledger plate 21 fixed upon the felly of the` Wheel andl provided-on its inner edge with an upwardly and outwardly directed flange portion 22 engaging with the outside of a transversely tapered flange 23 on the underY side of the rim 12. For holding the ledger plate in place, I provide a plate 24 arranged at intervals on the outer side of the felly and secured thereon by means of a screwthreaded bolt 25, fitted in a socket 2G ernbedded in the felly. The plate 24 has its upper end an inwardly extending angular abutment 27 engaging with the outer end of the ledger plate and bearing against the outside of a transversely tapered flange 28, similar to flange 23, and formed also on the under surface of the rim 12. The plate 24 is provided with an elongated opening 29 where the bolt 25 passes through, so that it may be moved radially on the telly to facilitate the removal of the rim.

In operation, the tightening of the bolts 25 locks the flanges 23 and 28 in place between the angular extensions 22 and 27,

thereby securing the rim in place. Obviously, this construction offers advantages of adjustment to replace wear and maintains the rim`securely in place'at all times.

ous parts may be resorted to without departing from the spirit of my invention as disclosed in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- -i l. In combination, a wheel, a slanted rim therefor of greater diameter at its inner edge than at its outer edge, the outer edge of the rim being provided Witli a peripheral channel, a tirelretaning flange on the inner edge of the rim, a removable leveling ring on the outer edge of the rim, a tire-retaining flange on the ring, and a locking ring engaged in the rim channel and provided with a flat side to abut and lock the leveling ring to the rim.
